+## Tutorials
+
+* [fmctutorial](https://git.tronto.net/fmctutorial): an in-depth
+  tutorial for the Rubik's cube *Fewest Moves Challenge*, or FMC.
+
+## Programs and scripts
+
+I started writing code in 2005, with a toy programming language called Dark
+Basic first and with Java shortly after that. In the past I enjoyed learning
+different programming languages (C++, J, Python...), but I have recently found
+more pleasure in writing software in plain C.
+
+* [nissy](https://git.tronto.net/nissy): A Rubik's cube solver,
+  intended primarily as a tool for practicing FMC.
+* [sdep](https://git.tronto.net/sdep): A minimalistic
+  "date+event" line parser. Can be used in combination with some shell scripts
+  as a reminder / calendar application.
+* [scripts](https://git.tronto.net/scripts): Various scripts
+  for Unix-like systems.
+
+## Math courses and programs
+
+Here are some scripts I wrote and lecture notes for some courses
+I taught at the [University of Luxembourg](https://wwwen.uni.lu)
+(2018-2022).
+
+* [mathsoftware](https://git.tronto.net/mathsoftware): a full
+  course (3 ECTS) on LaTeX and SageMath.
+* [preplogic](https://git.tronto.net/preplogic): notes and
+  exercises for two introductory lectures on elementary logic.
+* [kummer-degrees](https://git.tronto.net/kummer-degrees): a
+  SageMath script for computing the degrees of Kummer extensions of the
+  rational numbers.
+* [arithmeticbilliard](https://git.tronto.net/arithmeticbilliard):
+  a python program for drawing the path of 2- and 3-dimensional arithmetic
+  billiards.
